13, the pivots 13 having their` axes in a plane passing horizontally through the center of the operating rod and equalty distant therefrom, one on either side thereof. The upper ends ot these parallel levers are mounted on studs 1%, 14, secured to the lower end ot the bacl standard 10. rThis standard is pivotally secured to the bach-support ing bar T by means ot the engagement ot circular tlanges 9 and ll above referred to. Bar 7 and standard 10 are held Vin coacting position by any suitable means which shall not interfere with the rotative engagemen of flanges Sl andi11. shown. thisl means may comprise a pin 15 extending through bars 'T and standard 10 at the center of the enlargement S ol said bar. llin 15 may be providedg if desired. with a portion 15 of enlarged diameter between the bar and standard, and with heads or locking pins or the like at each end ot' the pin to hold the same in place. preferably be provided about pin 15 in its passage through bar l and standard 10'to prevent the saine taking the strain which would otherwise be transmitted through flanges 11 and 9.

The studs 1l on which the upper ends of. parallel lever 13 are mounted are located on opposite sides ot pin 15. at equal distances from said piu, studs 11- bei ng separated by a slightly greater distance than the pivots 13 at the lower ends ot' levers A13, rlfhe lerers 13 are bent outwardly at their ends, their main portions lying close together and slightly overlapping during the movements ot the back. These parallel levers maintain the back standard 1() in proper position during its swinging movement from one side oit the seat to the other. rthe pivots 1+i. being a slightly greater distance from pin 15 than the pivots at the lower ends ot the levers are trom the pivot o t the bar 7, the back standard will be given a slight rearward inclination when it is thrown to either oil its seating positions. as ihown in Fig. 1, it being understood that pin 15 is at the center ot rotation ot flanges t? and 11, and would constitute an additional connection between standard 1() and bar T it the circular [langes were not provided.

rlho back standard 10 is provided near its lower end and across the circular enlargement 12 with an outwardly extending tlange 1G which is adapted to come to rest on the slightly inclined flange 17 ot' the adjacent end-plate, as is shown in Figs. 1, 3 and 4c ot the drawings. The inclination given to the back standard in each of its operative positions by reason ot the arrangement ot levers 1.3 is sullicient to permit the [lange 16 to seat squarely on the ilange 17 at each end ot the end frame f1, the coaction of flanges 1G and 1T thus supporting the baci: standard at the rearwardly and upwardly inclined angle small clearance should` which is desirable tor the back. As is shown in the drawings, Figs. 1 to 4, the iange 16 extends entirely across the enlargement- 12 oi the bacl; standard 10 at right angles to the longitudinal center line of the back standard; also the supporting flange 1T is cutaway at each end of the seat end et, as is indicated at 1T. Accordingly aportion ot' flange 16 at one side ot the centerline vol5 the standard will come to rest on the flange 1T when the back is in one of its seating positions, while a portion of the iiange 16 on the opposite side of the center line will come to rest on the [lange 1T at the opposite end ot' the seat end, when the back is in its opposite seating' position. The reason tor this preferred arrangement will be explained hereafter. Y

Pressure applied in a rearward4 direction to the back-cushion, either because ot' the pressure otI the bacl; oit the occupant of the seat against the seat back, or because of the `torce exerted in reversing the seat back into one oit its seating positions, imil arts a turning elfeet to the back and the standards 10 about the axis 15 oit the pivotal or rotative connection between the standard and itssupporting bar 'i'. Yliuch tilt-ing or rotative ettect would put an objectionable shearing stress on the pivots 14 of levers 1B. rlhis etl'ect would not be overcome b y the seating otl ilange 16 on flange 17, either for the full length of flange 16 or tor part oll its length, as shown, because the standard would tend to pivot about the rea 1' end of flange 16. Accordingly, l prov' 'le coactingrlanges or stops suitably arranged on the end plate and stainlard to preif'ent such rotation of the bach and to relieve the operating mechanism of the strains otherwise occasioned thereby. These locking flanges comprise a pair of vllanges 18 and 19 vformed on the standard and a coacting llange. 20 at each end ot' the end-plate i. VFlanges 1S and 19 incline upwardly, one toward the left and the other toward the right, some distance below axial pin 15.V Theseflanges may suitably be positioned at each side of the longitudinal center line the standard with their lower ends joining. Flanges 2O incline upwardly, the one at the leit hand end ot' the end-plate toward the right and the one at the right hand end of the end-plate toward the lett. Flanges 2O are so inclined and arranged that the flange 1S on thel standard will come squarely into contact with the tlange 20 at lthe right hand end ot the end-plate, and flange. 19 will corne squarely into cont-act with flange 2O at the left hand end of the end plate when the back reaches its seating position at each edge of the seat. ment ot tlanges 1S and 19 as the bach approaches a seating posit-ion is the resultant ot the .movement ot' axis 15 about operating rod 5 as a center as bar T swings over, and

It will be noted that the` movethe slight, rotation in the opposite direction l of standard about axis 15 due to lthe aetion of pa 'allel levers 13.

' llanges 20 and the coasting flanges on th stanr ard are inclined upwardly at an angle which is sn'fiioiently sharp to pre 'ent zny rotation of standard 10 about axis 15 as a Center because of pressure applied to the haelt above axis 15. ft is obvious that pressnreapplied to the hack above axis tending to tilt the back rear-wardly` presses the flange 18 or 19 firnil;v against 'flange 2O with a resultant positive locking ol' vthe hack against snoh movement. It is obvious that the pressure of 'flange 1S, fo; example, against flange 20, due to the tilting move,n nient referred to, `is exerted in the direction or' the tangent to a circle drawn about the axis 15 as a Gente at each point of the lange 1S. iliooordinoly, a positive loolr is effected when the flange 2O is of an inclina-tion con.- siderahly steeper than this tangent7 aange 90 being located below the Center of rotaition lf sealing flange 16 on the bach standard. rests "or i entire length on flange 1'(g there ,noen'a rer the hack standard to pivot t i end of flange 16, when haeltM wai-diy directed pressure is agplied to the haelt ahore axis 15. lt not prevented by the interposition of flanges 1S and 20 or 19 and 20, jihis would tend to Cause a straightening ont ot' the angle between standard 10v and arin T, the rear end oil. lange 15 riding along flange 1i'. ln tl construction illustrated, this pivotal niofenientwould apply objectionable pressure to pivots 14, lll of levers 13 if flanges 18 and 2O or 19 and Q0 did not prevent. Even with looking flanges 18, 19 and Q0 there niight he a slight pivotal movement about the rear end of flange 1G unless the anglo ot' flange 2O and the coasting i'lange 1S 19 were, steeper than it otherwise would have to he. rl`his difficulty may he overcome lo' cutting away the seating fiaifige ii" for a (llistanoe at each end of the end-plate, as illustrated at il, such that the fange 1G l as a hearing on the vflange 17 'for .hioh extends toward the adjacent vhe end-plate onlyY to the longitudinal no of" the haelt standardror to a point somewhat. ort il the longitudinal center lino as il nstrated. "lilith tais eonstruotion the rearniosi hearing point of flanoe 15 is of the axes 15, so that 'Wh haelt- ;rnin pressure is applied to the haelr, there is no po oit Contact between flanges 15 and 1? to thel rear oil the pivotal aXis 15 which could act :is a filler iin to canse.

It will, of course, be understood that the important feature of this invention is the locking of the back standard to a rigid part of the seat support in order to relieve the pivots and other parts of the back transporting mechanism of the backward tilting strains brought thereon when the seat is in use, this feature being combined as described, in the preferred form of my invention, with the circular interlocking bearing flanges con'iprising the pivotal connection between the standard and back-supporting bar. lVhile I have shown a seat movement in which parallel levers 13, 13 are used to govern the inclination of' the back, it should be understood that the invention is not restricted to this type of seat. It should also be understood that while the operating parts are shown for only one end of the seat, the said parts will be duplicated at the opposite end, unless equivalent niechanisni is there used.
